Grove - High Temperature Sensor
Thermocouples are very sensitive devices. It requires a good amplifier with cold-junction compensation. The Grove - High Temperatire Sensor uses a K-Type themocouple and a thermocouple amplifier that measures ambient temperature using thermistor for cold-junction compensation. The detectable range of this Sensor is -50-600°C , and the accuracy is ±(2.0% + 2°C)
- Voltage：3.3 ~ 5V
- Max power rating at 25℃ ：300mW
- Operating temperature range：-40 ~ +125 ℃
- The temperature measurement range is (-50 ~ +600℃)
- Amplifier output voltage range (0 ~ 3.3 V) mv
- Cold junction compensation (environment temperature measurement)
- Thermocouple temperature measurement accuracy of + / - 2.0% (+ 2 ℃)
More details about Grove modules please refer to Grove System
Here is an example to show you how to read temperature information from the sensor.
We need a Seeeduino V3.0 and a Grove - High Temperature Sensor.
A4 and A5 are the I2C lines of Seeduino. Plug the sensor to the I2C port of Seeeduino to read data.
Download Code and Upload
You can download the library from here
Then extract the library to the Library folder of Arduino, open the demo in examples folder.
Then upload it to your Seeeduino.
Open Serial Monitor and Get Data
Then, open your Serial Monitor, you can find the temperature in Celsius here.

The platforms mentioned above as supported is/are an indication of the module's hardware or theoritical compatibility. We only provide software library or code examples for Arduino platform in most cases. It is not possible to provide software library / demo code for all possible MCU platforms. Hence, users have to write their own software library.
For any technical issue, you are most welcome to contact email@example.com, our techsupport engineers will help you. Thank you!
Help us make it better
Welcome to the new documentation system of Seeed Studio. We have made a lot of progress comparing to the old wiki system and will continue to improve it to make it more user friendly and helpful. The improvement can't be done without your kindly feedback. If you have any suggestions or findings, you are most welcome to submit the amended version as our contributor via Github or give us suggestions in the survey below, it would be more appreciated if you could leave your email so that we can reply to you. Happy Hacking!
